What your IBM BladeCenter JS20 Type 8842 offers
Your blade server is designed to take advantage of advancements in memory
management and data storage. Your blade server includes:
IBM PowerPC
IBM PowerPC 970 microarchitecture technology leverages proven innovative IBM
technologies to build powerful, scalable, reliable IBM-processor-based servers.
PowerPC 970 microarchitecture technology includes features such as light path
diagnostics, Predictive Failure Analysis (PFA), and Advanced System
Management.
Impressive performance using the latest microprocessor technology
Your blade server supports two IBM PowerPC 970 microprocessors and comes
with two microprocessors installed. Together, these two microprocessors enhance
performance. With two microprocessors, your blade server can operate as a
symmetric multiprocessing (SMP) server. With SMP, certain operating systems
and application programs can distribute the processing load between the
microprocessors. To use SMP, obtain an SMP-capable operating system. For a
list of supported operating systems and other options, go to
http://www.ibm.com/pc/us/compat/.
Integrated network environment support
Your blade server comes with one integrated dual-port Gigabit Ethernet controller.
Each Ethernet controller port has an interface for connecting to
10/100/1000-Mbps networks through an Ethernet-compatible switch module on
the BladeCenter unit. The blade server automatically selects between 10BASE-T
and 100/1000BASE-TX environments. Each controller port provides full-duplex
(FDX) capability, which enables simultaneous transmission and reception of data
the Ethernet local area network (LAN). The controller supports Wake on LAN
technology.
I/O expansion
Your blade server comes with two connectors on the system board for an
optional I/O expansion card for adding more network communication capabilities
the blade server.
Large system memory
The memory bus in your blade server supports up to 4 GB of system memory.
The memory controller provides support for up to four industry-standard 2.5 V,
184-pin, double-data-rate (DDR), PC2700, registered synchronous dynamic
random-access memory (SDRAM) with error correcting code (ECC) dual inline
memory modules (DIMMs). For the most current list of supported DIMMs, see the
ServerProven
Light path diagnostics
Light path diagnostics provides light-emitting diodes (LEDs) to assist in isolating
problems with the blade server. An LED on the blade-server control panel is lit if
unusual condition or a problem occurs. If this happens, you can look at the
LEDs on the system board to locate the source of the problem. For more
information, see “Light path diagnostics overview” on page 92.
Serial Over LAN
Your blade server supports Serial Over LAN (SOL) technology, which provides
advanced remote management capability. It provides the ability to redirect server
serial data over a LAN without the use of serial concentrators. It also eliminates
the need for serial cabling by internally rerouting serial packets over the LAN.

Chapter 2. Blade server power, controls, and indicators
This chapter describes the power features, how to turn on and turn off the blade
server, and what the controls and indicators mean.
Turning on the blade server
Important: To generate faster blade-server startups from the network, connect the
dynamic host configuration protocol (DHCP) server to the Ethernet switch module in
I/O bay 2 in the BladeCenter unit. The system firmware code in the blade server
detects this Ethernet controller first. The Ethernet controller in each blade server is
then associated with the switch module in I/O bay 2.
Notes:
After you connect the power cords of your BladeCenter unit to the electrical
outlets, wait until the power-on LED on the blade server flashes slowly before
pressing the blade server power-control button. Before the LED flashes, the
service processor in the BladeCenter management module is initializing, and the
power-control button on the blade server will not respond.
While the blade server is powering up, the power-on LED on the front of the
server is lit. See “Blade server controls and LEDs” on page 15 for the power-on
LED states.
After an orderly shutdown of the operating system occurs, the Wake on LAN
feature is permanently enabled in the blade server system firmware code.
Therefore, Enabled is the default setting. The Wake on LAN setting for each
blade server is stored in the management-module nonvolatile random-access
memory (NVRAM). To disable the Wake on LAN feature for one or more blade
servers, use the BladeCenter management-module Web interface. For more
information about the BladeCenter management-module Web interface, see the
BladeCenter Management Module User’s Guide on the IBM BladeCenter
Documentation CD.
Throughout this document, the management-module Web-based user interface is
also known as the BladeCenter management-module Web interface.

This chapter provides instructions for adding options or customer-replaceable units
(CRUs) to your blade server. CRUs are customer-replaceable components, such as
memory modules, hard disk drives, and I/O expansion cards. (Some removal
instructions are provided in case you need to remove one option or CRU to install
another.)
Installation guidelines
Before you begin, read the following information:
Read the safety information beginning on page vii and the guidelines in “Handling
static-sensitive devices.” This information will help you work safely with your
blade server and options.
Read the information in “Preinstallation requirements” on page 11.
Back up all important data before you make changes to disk drives.
For a list of supported options for your blade server, go to
http://www.ibm.com/pc/us/compat/.
Before you remove a hot-swap blade server from the BladeCenter unit, you must
shut down the operating system by typing the shutdown -h now command. If the
blade server was not turned off, press the power-control button (behind the
blade-server control panel door) to turn off the blade server. You do not have to
shut down the BladeCenter unit itself.
System reliability guidelines
help ensure proper cooling and system reliability, make sure that:
The ventilation holes on the blade server are not blocked.
Each of the blade bays on the front of the BladeCenter unit has a blade server or
filler blade installed. Do not operate the BladeCenter unit for more than 1 minute
without a blade server or filler blade installed in each blade bay.
You have followed the reliability guidelines in the documentation that comes with
the BladeCenter unit.
You have not installed any small computer system interface (SCSI) devices. The
blade server does not support SCSI devices. If you attach SCSI devices to the
blade server, these devices will not be recognized or configured, and they will not
operate.

Installing memory modules
You can increase the amount of memory in your blade server by installing additional
memory-module options. When you install memory, you must install a pair of
matched dual inline memory modules (DIMMs).
Notes:
The system board contains four DIMM connectors and supports two-way memory
interleaving.
The DIMM options available for your blade server are 256 MB, 512 MB, and 1
GB. Your blade server supports a minimum of 512 MB and a maximum of 4 GB
system memory.
Both DIMMs in a pair must be the same size, speed, type, and technology. You
can mix compatible DIMMs from various manufacturers.
The second pair of DIMMs does not have to be the same size, speed, type, and
technology as the first pair.
The blade server does not support unregistered DIMMs. Install only 2.5 V,
184-pin, double-data-rate (DDR), PC2700, registered synchronous dynamic
random-access memory (SDRAM) with error correcting code (ECC) DIMMs.
These DIMMs must be compatible with the latest PC2700 SDRAM Registered
DIMM specification, which is available from http://www.jedec.org/. For a list of
supported options for your blade server, go to http://www.ibm.com/pc/us/compat/.
PC2700 DIMMs are compatible with earlier specifications and work in the
PC2100 and PC1600 DIMM connectors.
Installing or removing DIMMs changes the configuration information for the blade
server. After you install or remove a DIMM, the new configuration information is
automatically saved in the blade server firmware code. You can verify the latest
configuration information by viewing the blade server firmware code as described
“Updating the firmware code for your blade server and the service processor”
page 55.

Complete the following steps to install a DIMM:
Read the safety information beginning on page vii and “Installation guidelines”
page 21.
the blade server is operating, shut down the operating system by typing the
shutdown -h now command. If the blade server was not turned off, press the
power-control button (behind the blade-server control panel door) to turn off the
blade server. See “Blade server controls and LEDs” on page 15 for more
information about the location of the power-control button.
Remove the blade server from the BladeCenter unit. See “Removing the blade
server from the BladeCenter unit” on page 23 for instructions.
Carefully place the blade server on a flat, static-protective surface.
Open the blade server cover. See “Opening the blade server cover” on page 24

Installing an I/O expansion card
You can add an optional I/O expansion card (adapter) to your blade server to give
the blade server additional network connections for communicating on a network.
When you add an I/O expansion card, you must make sure that the switch modules
I/O bays 3 and 4 on the BladeCenter unit both support the I/O expansion card
network-interface type. For example, if you add an Ethernet expansion card to your
blade server, the modules in I/O bays 3 and 4 on the BladeCenter unit must both
compatible with the Ethernet expansion card. All other I/O expansion cards
installed on other blade servers in the BladeCenter unit must also be compatible
with these switch modules. In this example, you could then install two Ethernet
switch modules, two pass-thru modules, or one Ethernet switch module and one
pass-thru module. Because pass-thru modules are compatible with a variety of I/O
expansion cards, installing two pass-thru modules would allow use of several
different types of compatible I/O expansion cards within the same BladeCenter unit.
Important:
Installation of an I/O expansion card requires removal of the hard disk drive that
installed in IDE connector 2. The I/O expansion card occupies the same space
this hard disk drive and replaces it. You cannot install a hard disk drive in IDE
connector 2 while an I/O expansion card is installed in the blade server.
When you install a Myrinet Cluster Expansion Card for IBM Eserver
BladeCenter into a BladeCenter JS20 Type 8842, you must connect the cable
from the I/O expansion card to the J7 connector on the system board.
Attention: If the hard disk drive installed in IDE connector 2 contains any
information that you want to keep, back it up to another storage device.
The following illustration shows how to install an I/O expansion card on the blade
server. The card is installed near IDE connector 2.

Installing an Ethernet cable
One dual-port Gigabit Ethernet controller is integrated on the BladeCenter JS20
Type 8842 system board. To support Ethernet connections and the SOL feature and
configure your blade server, you must install an optional Ethernet-compatible
switch module, such as the Nortel Networks Layer 2-7 GbE Switch Module for IBM
Eserver BladeCenter or IBM 4-Port Gb Ethernet Switch Module for BladeCenter,
I/O bay 1 of the BladeCenter unit.
you plan to use both Ethernet controller ports, you must install an identical
Ethernet switch module in I/O bays 1 and 2, since both I/O bays require the same
type of optional Ethernet-compatible switch module. Each controller port provides a
1000-Mbps full-duplex interface for connecting to one of the Ethernet-compatible
switch modules in I/O bays 1 and 2. If you plan to attach additional Ethernet
devices to the blade server or the BladeCenter unit, you must install an optional
Ethernet-compatible switch module, such as the Nortel Networks Layer 2-7 GbE
Switch Module for IBM Eserver BladeCenter or IBM 4-Port Gb Ethernet Switch
Module for BladeCenter, in I/O bay 3 or 4 of the BladeCenter unit, to support these

additional Ethernet connections. If you install optional Ethernet-compatible switch
modules in I/O bays 3 and 4, these switch modules must be identical.
The optional Ethernet switch modules contain four ports with RJ-45 connectors.
These connectors provide a 10/100/1000 Base-T interface (either at half-duplex or
full duplex) for connecting twisted-pair cable to the Ethernet network. You must
purchase and install a compatible cable to connect these devices. To connect an
Ethernet controller port to a repeater or switch module, use an unshielded twisted
pair (UTP) cable with RJ-45 connectors at both ends. For 100 Mbps or higher
operation, Category 5 cabling is required. For 10 Mbps operation, Category 3
cabling is required.
Notes:
For more information about Ethernet requirements, see the documentation that
comes with the Ethernet devices and the Eserver BladeCenter Type 8677
Installation and User’s Guide on the IBM BladeCenter Documentation CD.
For more information about the Ethernet switch modules, see the IBM 4-Port Gb
Ethernet Switch Module for BladeCenter Installation and User’s Guide or Nortel
Networks Layer 2-7 GbE Switch Module for IBM BladeCenter Installation Guide

Note the machine type, model number, and serial number on the blade-server
bezel assembly. You will need this information to complete this step.
Your replacement system board comes with a repair identification (RID) tag
label. To ensure future entitlement for service, you must write the serial
number of the original system board onto the RID tag label in this step. The
part number for the RID tag is 13N0477.
Use the RID tag label to transfer entitlement (machine type, model number,
and serial number) from the previous blade server to the new blade server. Do
not use a pencil or felt-tip pen to complete the RID tag label.
Important:
The serial number of the failing system board must match the serial number
that you reported when you called IBM for service.
Because the new system board does not have a serial number, you must
transfer the original system-board serial number to the new system board.
The first time that you turn on the new blade server, the firmware code will
request that you enter the serial number. You must enter the original
system-board serial number. If you enter a different serial number, the
operating system that you installed might interpret this information as an
incorrect serial number, and you might have to change your

Chapter 5. Configuring your blade server
This chapter contains instructions for establishing a Serial Over LAN (SOL)
connection, enabling the SOL feature, and configuring the blade server so that you
can run SOL sessions and use the BladeCenter management-module
command-line interface. This chapter also explains how to update and configure
BladeCenter components for SOL operation using the management-module
Web-based management and configuration program. The IBM Eserver
BladeCenter management-module command-line interface provides access to the
text-console command prompt on each blade server through an SOL connection,
enabling the blade servers to be managed from a remote location.
You also can perform many configuration procedures using the
management-module command-line interface. See the IBM Eserver BladeCenter
Management Module Command-Line Interface Reference Guide on the IBM
BladeCenter Documentation CD for information and instructions. In addition, you
can use the simple network management protocol (SNMP) to perform configuration
procedures. SNMP commands are described in the IBM Eserver BladeCenter
Management Module Command-Line Interface Reference Guide on the IBM
BladeCenter Documentation CD. For additional information about SNMP, see also
the IBM 4-Port Gb Ethernet Switch Module for BladeCenter Installation and User’s
Guide or Nortel Networks Layer 2-7 GbE Switch Module for IBM BladeCenter
Installation Guide on the IBM BladeCenter Documentation CD.
The firmware code in your blade server uses auto-configuration; therefore,
additional blade-server configuration programs are not required for the blade server.
However, if you have attached other devices to the blade server or the BladeCenter
unit, you must configure those devices as described in the applicable
documentation that comes with those devices or the BladeCenter unit. You do not
have to set any passwords to use the blade server. If you change the battery or
replace the system board, you must reset the date and time through your operating
system.
For information about setting up your network configuration for remote
management, see the IBM Eserver BladeCenter Planning and Installation Guide.
You can obtain the planning guide from the Web site at
http://www.ibm.com/pc/eserver/bladecenter.
Note: Before you can run programs on the blade server, you must establish an
SOL connection and install an operating system on the blade server. For
information about installing your operating system, see Chapter 7, “Installing
the operating system,” on page 61.
Using the Serial Over LAN (SOL) feature on the blade server
Before you can perform the following tasks, you must establish an SOL connection
and start an SOL session on the blade server:
Establishing a communications channel between the blade server and a
compatible monitor (or video console), keyboard, and mouse.
Installing the operating system on the blade server.
Configuring the SOL feature.
Running diagnostics programs.
Having the blade server serviced.

To support the SOL feature and to configure your blade server, you must install a
compatible Ethernet switch module in I/O bay 1 of the BladeCenter unit. Examples
compatible Ethernet switch modules are the IBM 4-Port Gb Ethernet Switch
Module for BladeCenter and the Nortel Networks Layer 2-7 GbE Switch Module for
IBM BladeCenter. For more information about these switch modules, see the IBM
4-Port Gb Ethernet Switch Module for BladeCenter Installation and User’s Guide or
Nortel Networks Layer 2-7 GbE Switch Module for IBM BladeCenter Installation
Guide on the IBM BladeCenter Documentation CD. For more details, see the
following information:
Chapter 6, “Running a Serial Over LAN session,” on page 57.
The IBM Eserver BladeCenter Management Module Command Line Interface
Reference Guide on the IBM BladeCenter Documentation CD.
Note:
The BladeCenter unit supports up to four Ethernet switch modules.
The SOL feature is accessed through the management-module command-line
interface. For information about using the command-line interface, see “Using the
command-line interface” on page 56 and the IBM Eserver BladeCenter
Management Module Command Line Interface Reference Guide on the IBM
BladeCenter Documentation CD.
Configuring the BladeCenter unit for the Serial Over LAN (SOL) feature
This section provides instructions for configuring the BladeCenter unit to operate
using SOL. The BladeCenter unit needs to be configured only once. The settings in
this section are used by all components in the BladeCenter unit. See “Configuring
the BladeCenter components for Serial Over LAN operation” on page 46 for SOL
configuration steps that are specific to each BladeCenter component.
SOL configuration that is shared by all BladeCenter components is performed using
the management-module Web-based user interface. The management-module
Web-based user interface supports only configuration and monitoring of the
command-line interface and SOL and cannot be used to start command-line
interface or SOL sessions.
Note: Throughout this document, the management-module Web-based user
interface is also known as the BladeCenter management-module Web
interface.
Some SOL configuration can also be performed using the management-module
command-line interface. See the IBM Eserver BladeCenter Management Module
Command-Line Interface Reference Guide on the IBM BladeCenter Documentation
for information and instructions.
After you install the operating system (including the Ethernet device drivers) on your
blade server, you can use either Telnet or Secure Shell (SSH) sessions to
communicate with the blade server. An SOL session must be used for the initial
installation of the operating system.
Before you continue with the configuration tasks, read the information in
“Preinstallation requirements” on page 11.

The default management-module SOL settings provide the best overall SOL
performance. You can modify these settings to meet requirements that are specific
your BladeCenter unit or network configuration. The default SOL values are as
follows:
Serial Over LAN: Enabled
Use this field to enable or disable SOL globally for the BladeCenter unit. The
SOL feature works only if SOL is enabled for the BladeCenter unit and the blade
server. If SOL is not already enabled for the blade server, you must enable SOL.

firmware update” on page 50
Management-module configuration
Before you configure the management module for SOL operation, review the
following information:
The management-module external network interface (eth0) configuration must be
valid for your production network. This configuration can be obtained from a
DHCP server or set statically.
The management-module internal network interface (eth1) and the Ethernet I/O
module configuration can be different from that of the management-module
external network interface (eth0); however, the management-module internal
network interface (eth1) and the Ethernet I/O module configuration must be in the
same subnet. The management-module internal interface (eth1) is exposed to
the external network through the management module; therefore, the
configuration must not conflict with any other addresses on your production
network. If you use a configuration for the Ethernet I/O module that is not valid
for your production network, you will not be able to update the firmware or
manage your Ethernet I/O module through the Telnet or the Web interfaces.

Configuring the Gigabit Ethernet controller
One dual-port Gigabit Ethernet controller is integrated on the blade server system
board. Each controller port provides a 1000-Mbps full-duplex interface for
connecting to one of the Ethernet-compatible switch modules in I/O bays 1 and 2,
which enables simultaneous transmission and reception of data on the Ethernet
local area network (LAN). Each Ethernet-controller port on the system board is
routed to a different switch module in I/O bay 1 or bay 2. The routing from the
Ethernet-controller port to the I/O bay will vary according to whether an Ethernet
adapter is enabled and the operating system that is installed. See “Blade server
Ethernet controller enumeration” for information about how to determine the routing
from the Ethernet-controller ports to I/O bays for your blade server.
Note: Other types of blade servers, such as the BladeCenter HS20 Type 8678, that
are installed in the same BladeCenter unit as this BladeCenter JS20 Type
8842 might have different requirements for Ethernet controller routing. See
the documentation that comes with the other blade servers for detailed
information.
You do not have to set any jumpers or configure the controllers for the blade server
operating system. However, you must install a device driver to enable the blade
server operating system to address the Ethernet-controller ports. For device drivers
and information about configuring your Ethernet-controller ports, see the Ethernet
software documentation that comes with your blade server, or contact your IBM
marketing representative or authorized reseller. For updated information about
configuring the controllers, go to the IBM Support Web site at
http://www.ibm.com/pc/support/.
Blade server Ethernet controller enumeration
The enumeration of the Ethernet controllers or controller ports in a blade server is
operating-system dependent. You can verify the Ethernet controller or controller port
designations that a blade server uses through your operating-system settings.
The routing of an Ethernet controller or controller port to a particular BladeCenter
unit I/O bay depends on the type of Ethernet expansion card that is installed. You
can verify which Ethernet-controller port in this blade server is routed to which I/O
bay by using the following test:
Install only one Ethernet switch module or pass-thru module, in I/O bay 1.
Make sure that the ports on the switch module or pass-thru module are enabled
(Switch Tasks → Management → Advanced Switch Management in the
BladeCenter management-module Web interface).

you enabled is associated with the switch module in I/O bay 1. The other
Ethernet-controller port in the blade server is associated with the switch module
I/O bay 2.
Communications from optional Ethernet adapters and other I/O expansion cards are

Updating the firmware code for your blade server and the service
processor
Your blade server contains firmware code. In addition, the service processor in your
blade server comes with its own firmware code. IBM will periodically make firmware
updates available for your blade server and the service processor. You can maintain
the latest levels of firmware code for your blade server and the service processor in
your blade server by installing firmware updates as they become available. Be sure
follow the instructions in this section.
Complete the following steps to view the current firmware code levels for your blade
server and the service processor:
Access and log onto the BladeCenter management-module Web interface as
described in the IBM Eserver BladeCenter Type 8677 Installation and User’s
Guide on the IBM BladeCenter Documentation CD.
From the Blade Tasks section, select Firmware VPD.
The Blade Server Firmware VPD window contains the build identifier, release, and
revision. Compare this information to the firmware information on the IBM Support
Web site at http://www.ibm.com/pc/support/. If these two types of information match,
then your blade server has the latest firmware code. If these two types of
information differ, download the latest firmware code from the IBM Support Web
site. Follow the update instructions on the IBM Support Web site.
apply the latest firmware code for your blade server service processor, flash the
service processor. Download the latest firmware code for your blade server service
processor from the IBM Support Web site at http://www.ibm.com/pc/support/. Use
the BladeCenter management-module Web interface to flash the service processor.
Follow the update instructions on the IBM Support Web site.
Important: To avoid problems and to maintain proper system performance, always
make sure that the blade server firmware code, service processor code,
and diagnostic firmware code levels are consistent for all blade servers
within the BladeCenter unit.

Using the command-line interface
The IBM Eserver BladeCenter management-module command-line interface
provides direct access to BladeCenter management functions as an alternative to
using the BladeCenter management-module Web interface. Using the
command-line interface, you can issue commands to control the power and
configuration of the blade server and other components installed in the BladeCenter
unit. The command-line interface also provides access to the text-console command
prompt for your blade server through an SOL connection. See the IBM Eserver

Chapter 6. Running a Serial Over LAN session
The IBM Eserver BladeCenter management-module command-line interface
provides a convenient method for entering commands that manage and monitor
BladeCenter components. The blade server does not support a direct connection to
monitor, keyboard, or mouse. Therefore, to enable communication between the
blade server and these devices, you must first configure the SOL feature on the
blade server to establish an SOL connection as described in Chapter 5,
“Configuring your blade server,” on page 41 and then start an SOL session as
described in this chapter.
This chapter contains the following information about running an SOL session:
Starting the command-line interface
Establishing a Telnet connection
Establishing a Secure Shell (SSH) connection
Starting an SOL session
Ending an SOL session
the BladeCenter environment, the integrated system management processor
(ISMP) and network interface card (NIC) on each blade server route the serial data
from the blade server serial communications port to the network infrastructure of the
BladeCenter unit, including an Ethernet compatible I/O module that supports SOL
communication. Configuration of BladeCenter components for SOL operation is
done through the BladeCenter management module (see Chapter 5, “Configuring
your blade server,” on page 41). The management module also acts as a proxy in
the network infrastructure to couple a client running a Telnet session with the
management module to an SOL session running on a blade server, enabling the
Telnet client to interact with the serial port of the blade server over the network.
Because all SOL traffic is controlled by and routed through the management
module, administrators can segregate the management traffic for the BladeCenter
unit from the data traffic of the blade servers.
start an SOL connection with a blade server, you must first start a Telnet
command-line interface session with the management module. When this Telnet
command-line interface session is running, you can start a remote console SOL
session with any blade server in the BladeCenter unit that is set up and enabled for
SOL operation. You can have as many as 14 simultaneous SOL sessions active
(one for each of up to 14 blade servers) with six additional command-line interface
sessions available for BladeCenter unit management. If security is a concern, you
can use SSH sessions to establish secure Telnet command-line interface sessions
with the BladeCenter management module before starting an SOL console redirect
session with a blade server.

See Chapter 5, “Configuring your blade server,” on page 41 for SOL setup
instructions and the documentation for your operating system for information about
commands that you can enter through an SOL connection. See the IBM Eserver
BladeCenter Management Module Command Line Interface Reference Guide for
information about:
Command-line interface guidelines
Command syntax and descriptions
Command-line interface error messages
Selecting the command target
You can use the command-line interface to target commands to the management
module or to other devices installed in the BladeCenter unit. The command-line
prompt indicates the persistent command environment: the environment where
commands are entered unless otherwise redirected. When a command-line
interface session is started, the persistent command environment is “system”; this
indicates that commands are being directed to the BladeCenter unit. See the IBM
Eserver BladeCenter Management Module Command Line Interface Reference
Guide for additional information.
Starting the command-line interface
Start the management-module command-line interface from a client computer by
establishing a Telnet connection to the IP address of the management module or by
establishing an SSH connection. You can establish up to 14 separate Telnet or SSH
sessions to the BladeCenter management module.
Although a remote network administrator can access the management-module
command-line interface through Telnet, this method does not provide a secure
connection. As a secure alternative to using Telnet to access the command-line
interface, SSH ensures that all data that is sent over the network is encrypted and
secure.
The following SSH clients are available. Although some SSH clients have been
tested, support or nonsupport of any particular SSH client is not implied.
The SSH clients distributed with operating systems such as SUSE LINUX, Red
Hat Linux, AIX®, and UNIX
information). The SSH client of Red Hat Linux 8.0 Professional was used to test
the command-line interface.

Chapter 7. Installing the operating system
Important:
Before you install the operating system on the blade server, make sure that you
provide an SOL connection between the blade server and a compatible monitor
(or video console), keyboard, and mouse. You must do this because the blade
server does not support a direct connection to these devices. The SOL
connection serves as a communications channel between the blade server and
these devices. The SOL feature must be enabled for both the BladeCenter unit
and the blade server before you can start an SOL session with the blade server.
Therefore, do not disable this feature. If you have not already done so, you must
configure the SOL feature on the blade server to establish an SOL connection
and enable the SOL feature as described in Chapter 5, “Configuring your blade
server,” on page 41 and start an SOL session as described in Chapter 6,
“Running a Serial Over LAN session,” on page 57.
See the IBM Eserver BladeCenter Management Module Command Line
Interface Reference Guide for information about SOL commands. See your
operating-system documentation for information about SOL commands that you
can enter using the command-line interface.
you plan to install the operating system through the Ethernet network, you must
install a second Ethernet switch module into I/O bay 2 of the BladeCenter unit.
For additional information, see Chapter 5, “Configuring your blade server,” on
page 41.
Note: This Ethernet switch module must be of the same type that you installed
I/O bay 1 of the BladeCenter unit.
After you install the operating system on your blade server, you must install any
service packs or update packages that come with the operating system. For
additional information, see the instructions that come with your operating-system
documentation and the service packs or update packages.
The BladeCenter JS20 Type 8842 has no external USB ports; however, it can
communicate with and use the USB diskette drive and CD-ROM drive that are in
the BladeCenter unit chassis.
Due to SOL requirements, you must select or install network device drivers after
you install the operating system. This includes the BladeCenter JS20 Type 8842
